  • Applications

    2-Methyltricosane (CAS 1928-30-9) is a long-chain hydrocarbon commonly found in paraffin waxes and mineral oil fractions. In industrial manufacturing, it is often used as a high-boiling solvent or diluent for coatings, inks, and adhesive formulations, helping to adjust viscosity and drying behavior. As a component of paraffin wax, it contributes to wax-based polish and surface-protection formulations used in coatings and cosmetics. It may serve as a carrier or fixative in perfumery to modulate fragrance evaporation. It can act as a processing lubricant or friction-reducing additive in polymer processing and metalworking, aiding downstream fabrication. In analytical chemistry, it is sometimes employed as a GC calibration standard for long-chain hydrocarbon analysis. These roles are typical for long-chain alkanes in industrial, cosmetic, and formulation contexts, subject to local regulations and formulation limits.
